(A) In experiment 5, participants were shortly presented with a target stimulus for 50ms, 150ms, 450ms or 750ms, and after a short blank had to recognize the target in a display of four face images. For all presentation times used in experiment 5, performance of CP participants differed from controls (B), while there was no significant difference in reaction times (C). However, while controls responded faster with increasing presentation time, there was no significant influence of presentation time on CP reaction times (Likelihood-ratio test, ). (D) In experiment 6, participants were repeatedly presented target faces, which - after a total of 24 feedback trials - had to be recognized in a 2-alternative forced choice paradigm. During the test, faces were presented for variable durations (50ms, 150ms, 450ms or 750ms). Independent of the duration, CP participants performed worse than controls (E), without significant differences in reaction times (F).
